TWINE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 228,516, dated June 8, 1880.

Application filed April 3, 1880.

To all whom it may concern:

Be it known that I, JAMES A. OROOKER, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Twine-Gutter, of which the following is a specification.

My invention consists in combining two sliding knives with a lever and spring in such a manner that when the lever is depressed the cutting-edges of ihe two knives are brought together, the action of the spring serving to keep them apart. The shanks of these two knives, together with the spring and operating mechanism, are inclosed in a convenient handle.

The exact nature of my invention may be best understood by reference to the drawings and specification.

In the drawings, Figure 1 is a sectional view of the handle, showing the spring and the two knives in elevation, the position of the operating-lever being indicated by dotted lines. Fig. 2 shows the interior of one of the pieces, which, when combined, as shown in Fig. 5, form the hollow handle. Figs. 3 and 4 are representations of the lever. Fig. 5 is a section through the entire device, taken at right angles to the cutting-blade. Fig. 6 is adetail, to show the position of aspring that serves to keep the cutting-blades in close contact with each other. Fig. 7 shows the two cuttingblades in plan.

Let A and B represent the two shells,which,' combined, as shown in Fig. 5, form the handle of the twineeutter.

H, Figs. 1, 2, and 5, is a stud, formed as shown, which serves as a guide for the two knives E and D, and also as a pivot for the (No model.)

lcverF to swing upon. The knife D is pressed upon by the spring S, which has a tendency to throw it forward.

The lever F, Figs. 1, 8, and 4, has two lugs upon itone,G, which engages with the notch 61' in the knife D. (See Figs. 1 and 7.) The other lug, G, is shorter, and engages with the notch e in the knife E. The position of this lever F is shown in Fig. 5, it being pivoted upon the stud H and rests upon the knife E.

K, Figs. 5 and 6, is a flat spring which presses against the knife D and holds it against the knife E.

The operation of my device is as follows: The twine to be cut is placed between the knives then by pressing the lever F the lugs G and G move about the pivot H. The lug G in the notch (Z draws the knife D backward, while the lug Gr in the notch c throws the knife E forward, thus bringing the two cuttingedges together.

Having thus described my invention, what I desire to secure by Letters Patent is-- 1. In a twine-cutter, the-combination of the lever F, having lugs G G, with the cuttingblades D and E, all operating together substantially as described, and for the purpose set forth.

2. In a twine-cutter, the combination of the handle A, the two cutting-blades E and D, and the opening-spring S with the closinglever F, the lugs Gr G, and the spring K, all operating together substantially as described, and for the purpose set forth.
